synthesis of amido alkylnaphthols using nano-magnetic particles and surfactants

we used dbsa and nano-magnetic for the synthesis of amido alkylnaphtols.

Synthesis of sulfonimidamides from sulfinamides by oxidation with N-chlorosuccinimide

BACKGROUND The synthesis of sulfonimidamides involves the nucleophilic substitution of a sulfonimidoyl chloride with an amine. However, only four chlorinating systems have been reported for the preparation of the sulfonimidoyl chloride intermediates. Whereas some of them have shown a rather limited substrate spectrum, the most versatile and commonly used tert-butyl hypochlorite is known to be e...

single-step synthesis of multi-component spirobarbiturates using ionic liquids and synthesis of substituted pyridine filled with catalysts supported on solid substrate

in this thesis, a better reaction conditions for the synthesis of spirobarbiturates catalyzed by task-specific ionic liquid (2-hydroxy-n-(2-hydroxyethyl)-n,n-dimethylethanaminium formate), calcium hypochlorite ca(ocl)2 or n-bromosuccinimide (nbs) in the presence of water at room temperature by ultrasonic technique is provided. the design and synthesis of spirocycles is a challenging task becaus...

Flow injection chemiluminescence determination of N-bromosuccinimide and N-chlorosuccinimide.

Efficient DBU accelerated synthesis of 18 F - labelled trifluoroacetamides † Antonio Bermejo

Due to the favourable properties of fluorine, approximately one fifth of newly registered small drugmolecules are organofluorine compounds. Moreover, the artificial isotope F (t1/2 109.8 min) has suitable nuclear properties for in vivo imaging in human subjects using positron emission tomography (PET). Hence, there is a large demand for efficient fluorination methodologies in both medicinal and...
